Mexican Case:
Using Smart Self-Managed Metering System
Patent Granted in Mexico, Patent Granted and/or Pending in Several Countries of the World
April 20 – 21, 2010, Bogota, COLOMBIA
México Data
�Covers almost 2 million square kilometers.�The fifth largest country in the Americas.� With an estimated population of 111 million. �It is the 11th most populous country.� The national power utility is CFE (Federal Commission of Electricity).
April 20 – 21, 2010, Bogota, COLOMBIA
CFE Characteristics
� CFE has 177 generation plants with capacity of 50,200 MW.
� Mexico has 33 million of electricity meters, 20% are poly-phase meters.
� The average consumption of the 80% of the users is 150 kWh/month, 5 kWh /day. This represents the 20% of the utility's income.
April 20 – 21, 2010, Bogota, COLOMBIA
� 12,000 readers.
� Billing process is each 2 months, average billing is 300 kWh.
� The user base grows 1.3 million each year.
� 12% no-technical loses.
� Few CFE offices to receive payments and short labor hours.
� CFE looked for the best technology suitable to Mexican characteristics.
CFE Characteristics
April 20 – 21, 2010, Bogota, COLOMBIA
Mexican Users Characteristics
� 80% users are low Income.
� 80% user have a low consumption of energy (3-5 kWh/day).
� Users receive they income payment per week .
� Users commute a long distance to make the energy service payment.

Background
� IUSA is the leader in the manufacture of meters in Mexico.
� With modernization, IUSA has new challenges to face.
� Questions and dilemmas about the right technology for the Mexican market.
� We analyzed several options of communications technologies, systems management.
� Several pilots tests in different states of Mexico.
� None of the existing technology has the necessary requirements for the Mexican market.
April 20 – 21, 2010, Bogota, COLOMBIA
Background
Our country has the following characteristics:
� Users with low income and low energy consumption.
� Expensive AMR, AMI technologies.
� Short-lived and changing technology.
April 20 – 21, 2010, Bogota, COLOMBIA
Background
� Meters hermetically sealed with tampering detection.
� Cost and effectiveness warranted in less than two years.
� IUSA didn’t find a solution that satisfied the requirements.
April 20 – 21, 2010, Bogota, COLOMBIA
Background
� CFE wasn’t sure about investing in a wide deployment of new electric meters with a different technology.
� IUSA developed a new system of electric meters to satisfy the needs of the Mexican market, which are:
April 20 – 21, 2010, Bogota, COLOMBIA
� Low product cost.
� Low installation cost.
� Meters with an outage included.
� Measurement and reporting components in the same meter.
� Energy-saving.
� Two ways user-utility communication.
� Easy to use.
� Can operate in prepayment or post-payment mode.
Background
April 20 – 21, 2010, Bogota, COLOMBIA
Background
� We researched the technologies available in the market.
� We decided to develop a prepayment technology because:
–Code-Technology is one-way and requires a keyboard to enter codes to the meter which makes it vulnerable.
April 20 – 21, 2010, Bogota, COLOMBIA
Background
� Card Technology can be two way with a chip, but this technology requires a slot in the meter.
� Remote reading technology with RF or PLC, works in two ways, but it has a high installation and communication cost.
April 20 – 21, 2010, Bogota, COLOMBIA
Background
One interesting alternative was found:
� The use of proximity cards with two-way communication technology
� Without slots and keyboards in the meter.
� It price is lower that the AMR and
� It is perfect for low income users.
April 20 – 21, 2010, Bogota, COLOMBIA
Background
We called this technology the
Smart Self Management
Metering System.
April 20 – 21, 2010, Bogota, COLOMBIA
Smart Self-Managed Metering System
� It is composed by a solid state electricity meter and a contactless smart card that works in a two-way communication.
� Measures the consumption of electricity, water and natural gas.
� Diminishes the financial and operating costs of utilities.
April 20 – 21, 2010, Bogota, COLOMBIA
Smart Self-Managed Metering System
� Facilitates a better consumption control for the consumer.
� Allows the user more payment options.
� Can operate either in post payment or prepayment mode.
April 20 – 21, 2010, Bogota, COLOMBIA
Benefits for the Utility
� Eliminates reading and billing cost $.
� Eliminates the connection and disconnection cost $.
� The Utility does not lose contact with the user, as the meter data updates each time the user recharges the smart card.
April 20 – 21, 2010, Bogota, COLOMBIA
Benefits for the Utility
� Detects tampering.
� The meter is installed in the same base of the actual meters.
� Doesn't require any preparation or to add a new communication system cost.
� The management system can transfer the meter’s data to the billing system of the utility.
April 20 – 21, 2010, Bogota, COLOMBIA
Benefits for the Users
� The users CONTROL the payment and consumption in accordance to their income.
� This system generates the culture of “if you save energy (water or gas) you save money”.
� This system avoids surprises of high payment amounts in the bill.
April 20 – 21, 2010, Bogota, COLOMBIA
